A nutrient is either a chemical element or compound used in an organism's metabolism or physiology. Six nutrient groups exist and are broadly classified into those providing energy, and those used as components in the body or cellular structures.[citation needed] A nutrient is essential to an organism if it cannot be synthesized in the organism and must be obtained from a food source.
